To all whom it. may concern,"-

.Be it known that i, HARRY LANDsninnL, a citizen of the United States,residingat Cincinnati, in thecou'ntyo'f Hamilton and State of Ohio, haveinvented certain new and usegtul Improvements in Shuttle CarriageMechanisni for Adding Machines, of Which the tollowingis aspecification. I

The mechanism of the present. invention is' particularly designed foruse in connection with adding machines Whi'chare intended to perm t therecording of itenis' n par-..

allel vertical coliimns, one of the columns, as for example the lefthand column, containing-items WlllCll are ordinarily employed asidentifying numbers or symbols,'and the fee '. listed, Without eitheradding-the item or ro-- tating the platen; lVith the parts-thuspoother Icolumn containing amounts which are intended to be-added into themachine. Thus, for example, in using the machine for-the purpose oflisting and recording the contents'of a number of freight cars, the,left hand column would be utilized,

for the purpose of listing the numbers of the cars While the right handcolumn fivould'be employed for recording the contents of each the totalresult. I

In a machine of this character, it isde'sirable to provide mechanism forautomatically andaddin the items of contents to secure shifting thecarriage transversely after each designating item has been listed, sothat the corresponding amountmay be recorded and added in the samehorizontal line; This necessitates the use of mechanism, actuated by thehandle pull for shifting-the carriage to the left after adesignating'iten'i has been sitioned to record anum'eral item, the mechanism is-entrained for the next succeeding handle pull to add in theitem last recorded, to feed the platen, andito restore the platen to theright hand position prior to the next operation. It is 'evidentthat onthe taking of a total or 'subtotah'only the'righthand c'olunni itemswill be included.

The inventiont'urther relates to thcmleans provided for disengaging thespecial shuttle.

. mechanism so as t-o .;r e'store the machine to its normal mode ofoperation The invention s an improvement over the one shown I anddescribed-intheLandsiedel Patent h'o.

corresponding 1n the. patent mentioned, the means for disabling .theadding mechanism are controlled bythelateral movement of the papercarriage, While-in the construction of the present invention said -meansare includedas a part of'thel device for shuttling" the paper carriage.e r I v The present invention also includes an improved method for.disabling the linespacing mechanism and other improvements Which will beapparent fro'm the fOllOWlDg ClQSCrip tionz I In the drawings:

In the drawings, the device has been ap-. plied to a Daltonaddingmachine Which in eludes a lateral stop carriage 1, type carit is notdeemed necessary toenter into a detailed description thereof, save in sofar as may be needtul to a full understanding of. the featurescomprising] the shuttling carriage --tion.

anti-triction devices beingprovided to r en'- able the platen carriageas a .Whole to travelbar 16, which is secured to and forms a part of thecarriage frame 12, as shown in Fi g. 2. The'swinging arm 14 is pivotedat its rear end to the pivotpin 17,. and the rear end 18 of the arm isdownturned through the flange 19 which carries the stud and is engagedby movement of the handle, so that one coma spring 20. Sufiicientclearance isaiforded between the arm 14 and the head of the stud 17 topermit the forward end of the arm 14 to be depressed against springtension'suiiicientlyto disengage a selected notch for the purpose ofreadjusting the platen carriage to a different lateral position. Thisenables various portions of the paper carried by the platen to bebrought to position to have columns of figures imprinted there-- It isobvious from the above description that asthe arm 14 is swung back andforth within the limits of its operation, it will shift the platenalternately to the right and left. The means provided for controllingthe swinging movements of the arm 14, in conformity with the movementsof the operating handle will now be described.

The arm 1% has pivoted thereto -a link 21, the outer end otwhich ispivoted eccentrically to a disk 22, which, during the operation of themachine, will be rotated intermittently in the same direction, beingmoved a half rotation with each return plate oscillation of the handlewill serve to throw the arm, and with it the platen carriage to theleft, and the next succeeding operation will throw the parts to theright.

The disk 22 is mounted upon a cross arm 23 rigidly mounted upon avertical shaft 2 1 journaled at its upper end through a bracket 25, andhas its lower end through a bracket The shaft near its lower end isprovided with a small pinion 2? which meshes with a large gear 28rotatably mounted upon a stud 29 upstanding from the bracket 26. Thegear 28 carries a ratchet plate 30 provided with notches 31 adapted to'co-act with a dog pivoted at its outer end to an arm 83, which latterat its inner end is pivoted upon a stud 29. The dog and arm areconnected by means of a spring 3 1 which serves to hold the dog inspring contact with the edge of the ratchet plate. 3y swinging the outerend of the'arm back and forth, intermittent rotation will be imparted tothe gear and parts associated thcrewitln The outer end of the arm 33 hasmounted thereon a roller which is engaged by a.

notch 36 in the plate or, which plate is secured to the inner end ofareciprocating slide bar 38. provided with guide slots .39 and 40 wh chengage guide pins 41 and 42 respectively, as lndicated in Fig, 2.

Reciprocations are imparted to the slide bar 38 by means of a link 13which is pivoted at its rear end to the slide bar 38 at. the point 4 1.The link atits forward end terminates in a hook 15 which engages a pin16 carried by the upper arm of a bell crank lever 1 7 which is pivotedto the stud 18 upon the side frame of the machine.

The lower arm of the bell-crank lever is engaged by a link it) which atits lower end is pivoted to a "segn'ient carried by the main handlecontrol shaft 6, so that with each -forward pull of the handle, theslide bar 38 will be moved rcarwardly and the dog retracted in positionto engage the next succeeding. notch on'the ratchet plate. lVith m theparts thus adjusted, the return movement of the handle will actuate thegearingand impart a-swinging movement to the arm which controls theshuttling of the platen carriage.

lVhen it is'desired to normalize the-operation of the machine, bydisabling the shuttling mechanism. this result is secured by the actionof a. disablinglevcr 51 which is iub crumcd upon a cross bar 52. Therear end of the disabling lever lies under a stud 53 inwardly extendingfrom the hooked'link 43, and the forward end 5-1: of the. disablinglever is liiit'urcated to receive the inturned end 55 of a beltcranklever 56 which. is pivoted at its elbow to a stud 57 carried by abracket 58 secured to the front wall of the machine, as shown in Figs. 2and 3. The bell crank lever is adapted to be swung back and forth bymeans ct an outwardlj, protruding finger piece 59 which engages apivoted spring controlled detent ($0 contigured-in its upper edge tohold the bell crank lever in either position of. adjustnient. By alateral movement oi the linger piece 52), the outer end oi? the bellcrank will be raised and lowered, thereby in'ipar'ting a like movc mentto the forward end otthe disabling lVhen the forward end of the dis- Themechanism for disabling the line spacing mechanism of the paper carriagewill now be described. The lower end of the vertical shaft 24 carries acam plate 1 hav ing a fiat side and an elevated side. Associated withthe cam is roller (3-3 mounted upon the rear'cnd of a slide bar (3provided on its upper edge with a cain'elevation (H. This cam elevation(3-1 co-acls with a roller (35 mounted upon. a swinging bracket 66freely pivoted upon the cross bar 52, which bracket carries an arm 67.The forward movements of the slide bar 63 will serve to thus elevate thearm 67, and this arm when elevated will engage with an arm 68 mounted,

upon a squared line spacing shaft 69, which shaft also carries a finger70 having a pawl 71 pivoted thereto, which pawl co-acts with the usualratchet wheel 72. These parts are actuated by a ,spring73 when theoperating lever ispulled forward and restored to their normal positionsby-a positive cam action,

' (not shown) on the return stroke in a manner common inthe-construction of adding machines. VVhen,.however, the arm 67 1slifted, it will-be noted that the arm 68 will be blocked. againstitsno'rinal forward. movemerit,- so that. the line spacing mechanismwill be disabled, and since these movements arecontro-lled by means ofthe cam 6-1 on the verticalshaft 24:, and since this shaft makes a halfrotation with each h'andle reciprocation,.it is evident that the linespacing mechanism will be disabled'on alternate operations of-thehandle, and that line spacing will occur only when the platen carriageis ,in its left hand positiomthat is to say, after a numerical item hasbeen introduced into the righthand column.

Means for disabling'the adding mechanism during the printing of an itemin the left hand column will now be described. lt-

is essential that the line spacing.mechanism and the adding mechanism behotlrdisabled at the same time, and the slide bar 63 is likewisc reliedupon to effect a disabling of the adding mechanism as well as the linespacing mechanism. 1 This bar is provided on its under edge with adepending linger 74; which engages a stud 75 on the upper arm of a bellcrank lever 7 6 which is pivoted on I a cross rod 77. The lower arm ofthe'bell crank lever is provided with a stud 7 8 which is adapted tocontrol the movements of a wipe pawl 79 which is pivotedto the usual vsegment 50 carried by the handle operated main shaft 6, a spring 81being provided to normally hold the rear or acting end of the wipe pawlin an elevated position. The wipe pawl co-acts with the usualmechanismprovided for lifting the bank of adding wheels-intoinesh with the usualadding racks 3 on the return stroke thereof. This mecha nisin, is oldand comprises a 'cam 82 and a;

plate 83 provided witli'studs' 84 The cam 82 is rigid on the shaft 85and when the latter is rotated by engagement of the rear end of the wipepawl-79 with one of the studs 84, the cam will berotated and theaddingwheels lifted into meshwith the racks in the usual HllIHDGYGXCQPtwhen the wipe pawl is thrown out of commission by the, disablingmechanism herein specially provided.

lVith the stud 78, in the depressed posiwhen the slide bar 63 is movedto itsrear motion, as indicated in 2.

tion shown Fig. 1, theforward end of the wipe pawl, as it is swungforwardly with the forward pull ofthe handle, will engage and ride overthe stud thereby throwing down the rear end of the wipe pawl to aninoperative position, so that upon the return movementof the handle andthe segment no actuation of the. addingwheel lifting devices willloeeffected. On the contrary,

position, and the stud 78 is lifted through the pull of the spring 86,the wipe pawl will occupy its normal position and upon its return.stroke will engage the stud 84: on the addmg wheel actuating series,there by permitting a movement,- upon the back order to readjust theplaten carriage to a different position laterally for the. purpose ofrecording numbers upon a different lateral section of the paper. Pivotedtc the upper. section of the fixed ball rail frame A .13 on the rearsidethereof is a tabulator latch 8 provided' with an i'ipstanding tongue88 whicn normally extends upwardlyandohliqucly therefrom in' a rearward.di-

The tonue occupies a position in roxib i mate relation to .a pair ofspaced transversely extending bars QOwhich are connected their endsbetween a pair of end plates 91 pivotally niounted between the carriageframes 11, one of said endplateslceing provided with a handle 92, sothat the two bars may be rocked 'ortilted in unison. These bars normallypresent their edges in parallel relation to the slotted tongue 88, whichedges are PIOYl'ClGCl at closely spaced intervals with notches 93.Corresponding notches in the upper and lower plates furnish points ofengagement for a plurality of yoke plates 94 (see Fig. 8).

The lateral edges 9430f the tabulator latch tongue 88 are bent back topresent a beveled front acting surface, and the latch as-a whole. ispivetally mounted for a rocking movement on the screw studs 96 which-con5 meet the latch with a lug 9 7 011 the rear upper rail of the fixedball'casting. To bet- .ter maintain the latch in pos tion, a pair of endtongues 98 lying within the slots 99 in the lug are provided and aspring 100 is connected at itsouter end to a tongue 101 and'ati .itsinner end to a fixed plate 102, tlierebyserving to normally hold the:latch forwardly, in which position the tongue 88 will. engage with. theedge of one of the yoke plates 94 when brought into register therewith.

engag'e1ne11t of the shuttling bar can be Integral with the latch is'a'rearwardly extending detent 103 which occupies a position immediatelyabove the pivot which connects the link 21 with the shuttling arm 14:,which latter, as previously explained, is loosely pivoted on the stud17, so that its end may be slightly depressed. The arrangement is suchthat when'the finger lever 92 is-depressed the notched bars are rockedor tilted causing the rear lower corner of the yoke plate 94: to bearagainst the latch tongue 88 in such a way to rock the latch and depressthe detent 108 which bears down onthe shuttling arm and permits adisengagement thereof from the notch in the tabulator bar. r

The yokes 94 are so located as to occupy positions .at or near theterminal points of movement of the shuttling arm, so that when thelatter is brought to rest in' eitherof its terminal positions, it willlie in proximate relation to the detent 103, .so th'ata dismade and arepositioning of the platen carriage effected.

the link 21' with the disk sion of numerous notches in the compamon bars90, permit the yoke plates to be located at positions corresponding tothe movements of the shuttling bar.

In operation, after an indicating'number has been set up in the usualstop carriage of 'themachine, with the platen, in its right handposition, and with the paper disposed to receive an impression in theleft hand or non-adding column, the handle will be pulled.

andthe figures printed .in the usual'manner. -With the parts adjustedforthis operation,

the adding mechanism and the line spacing mechanism will both bedisabled, so that the only operation special to the present invention,which takes place "on the return movement of the handle will be theshuttling of the carriage tothe left to bring the paper into position toreceive a numerical item in the right hand column and on the same hori-Zontal line with the designating item last iniprinted. After thenumerical item has been set up, the handle is again pu'lled',.but onthisoccasion, the parts are in such position that on the return stroke ofthe handle the adding wheels willbe in mesh with the racks, so that theitem will be accumulated, and simultaneously the line spacing mechanismwill operate to turn the platen sufficiently to line space the paper inpreparation for the imprinting of another designating item in the lefthand column.

By adjusting the stud 59, all of the mechanism, special to the presentinvention. is disentrained from the handle shaft, so that the machine asa whole may readily be re stored to operation as a regular adding niaforward I The shuttling The throw of the shuttling arm can be amplifiedor decreased by ra-- dially changing thepoint of attachment of and theprovi chine, in which case, of cause, the platen will operatecontinuously in one position, and the line spacing mechanism willoperate with each oscillation of the handle instead of with alternateoscillations as in the case when the shuttling devices are in service. Ifeatures ot-this invention are of such a nature that they can be readilyappliedto adding machines'of standard construction without-in any waychanging or modifying the general structure of the machine as a whole,since these devices. are fitted to occupy spacenot otherwise occupiedand are adapted to function without interference with thememainmgmechanisms.
